Still debugging - sigh! Eric told me about the missing HelloWorld.rsg file while compiling the HelloWorld example. I forgot to say that the HelloWorld.h file, before giving the "abld build armi urel" command, has to be modified. On line 38 change: #include <helloworld.rsg> to: #include <HelloWorld.rsg> because the HelloWorld.rsg header file is generated with the same name of the resource file (HelloWorld.rsc), only changing its extension; it's generated in the $EPOCROOT/epoc32/include directory (ouch!!!!). After changing the HelloWorld.h file you can start "abld build armi urel" and get it compiled without (I hope) errors. (thanks Eric!!) alf
